Is Daylight Saving Time Bad For You?

Hugh Pickens writes “According to experts on circadian rhythms, the hour shift in sleep schedule from Daylight Saving Time can have serious effects on some people’s health, particularly in people with certain pre-existing health problems. One study found that men were more likely to commit suicide during the first few weeks of Daylight Saving Time (DST) than at any other time during the year, and another study showed that the number of serious heart attacks jumps 6% to 10% on the first three workdays after DST begins. Dr. Xiaoyong Yang, an assistant professor of comparative medicine and cellular and molecular physiology at Yale University, theorizes that shifts in biologic rhythms could trigger harmful inflammatory or metabolic changes at the cellular level, to which these individuals may be more susceptible.”
